I would suggest you to uninstall and reinstall the Bluetooth driver. Please paste a screenshot of ‘Device Manager’ with ‘Network Adapters’ expended. you may follow the steps below:
- Press ‘Windows’ key + R on ‘Desktop’ screen.
- Type ‘devmgmt.msc’ in run box and press ‘Enter’.
- Click > sign next to ‘Network adapters’.
You may update the system BIOS. Please refer to the link: http://dell.to/11gI5U6.
